Answer:
1. Applying <u>the principle of original horizontality</u> -indicates that layers were repositioned from a flat-lying orientation.
2. Magma intrudes into layers of sedimentary rock and displaces them. We can deduce that the intruded magma that crystallizes is younger than the surrounding sedimentary layers by applying <u>the principle of crosscutting relationships</u>.
3. While visiting the Grand Canyon, you are amazed by the depth of layers of sedimentary rock before you, <u>the law of superposition</u>-- is evident here where progressively younger layers have formed over time and are stacked upon each other.
4. A fault cuts through layers of limestone, sandstone, and conglomerate. The surrounding layers must be <u>older</u> than the fault.
5. A mass of granite has inclusions of surrounding sandstone. The sandstone and surrounding layers show evidence of uplift over time. The granite must be <u>younger</u> than the sand deposits.
There is no skeleton, so no fossil. <span />
Answer:
5g will be left
Explanation:
Uranium 235 have a half-life of 700 million* years. This means that the element will decay to half its initial amount by that time. So if I start with 10g chunk of 235 Uranium, after 713 million years, only half of it (5g) will be remaining.
*the exact half life of Uranium 235 is 703,800,000 years.
